Water-curtain type self-cleaning range hood

Abstract

The invention discloses a water-curtain type self-cleaning range hood which comprises a machine shell (1) and a fan (2), wherein the fan (2) is arranged in the machine shell (1); an air inlet (1.1) is formed in the machine shell (1); a smoke deflector (1.2) is arranged in the machine shell (1) and is positioned at the rear side of the air inlet (1.1); the bottom of the machine shell (1) is provided with a water storage area (1.3), and the water storage area (1.3) is arranged under the smoke deflector (1.2); a water inlet (1.4) and a water outlet (1.5) are formed in the machine shell (1); the range hood is also provided with a water feed device used for feeding water into the water storage area (1.3); the distance (H) between the water surface in the water storage area (1.3) and the lowest position of the smoke deflector (1.2) is more than or equal to 0 and is less than 30mm. The range hood is provided with the water feed device, so that a tap water pipeline does not need to be laid during installation, and the range hood is more convenient to install; furthermore, a self-cleaning effect is realized.

Description

technical field [0001] The invention relates to kitchen utensils, more specifically to a water curtain type automatic cleaning range hood. Background technique [0002] The range hood is a commonly used household kitchen appliance. It can suck the oily fume and water vapor generated during the cooking process in the kitchen to the outside, so as to achieve the purpose of purifying the kitchen environment. However, during the working process of the range hood, the inner surface of the housing and the impeller will adhere to and deposit oil and dirt. If it is not cleaned in time, it will become very difficult to remove, and it will also affect the dynamic balance of the impeller of the range hood. Thereby affecting the suction capacity of the range hood. [0003] On March 16, 2011, the Chinese Patent Office disclosed a patent No. ZL2009100992858 "a range hood capable of separating oil and smoke". The water area is opposite, and the distance between the water surface in the w...

Problems solved by technology

[0004] 1. Since there are only water inlets and outlets on the casing of the range hood, the water storage area needs to be fed by tap water. Therefore, when using this type of range hood at home, it must be installed when the house is decorated. A water pipe outlet is preset near the location, but the general family purchases the range hood after the water pipe is laid, which brings obstacles to the use of the range hood

[0005] 2. Although the range hood has the effect of oil fume separation, it still cannot achieve 100% separation of oil fume, and dirt will still be deposited on the inner wall of the casing and the impeller, and this range hood cannot achieve the effect of automatic cleaning
